FIELD OF INVENTION

This invention describes a topical herbal formulation, useful for the prevention/treatment of dyshidrosis (pompholyx) or related skin disorders such as palmoplantar pustulosis, exfoliative keratolysis, contact dermatitis, eczema, ichthyosis and xerosis. The formulation is also lethal to fungus, mold, bacteria and yeasts, indicating potential to treat skin infections associated with invasive pathogens, such as dermatophyte fungi, staphylococci, streptococci, scabies, candida, aspergillus and scopulariopsis.

BACKGROUND OF INVENTION

Hand eczema is a prevalent skin disorder, encompassing a variety of diseases such as contact dermatitis and dyshidrosis (pompholyx) (Tamiya, Y. Nippon Ika Daigaku Zasshi 1994 61(4):286-94). Dyshidrosis is characterized by the initial symptoms of blistering and dry cracked skin on the hands or feet, affecting the tips and sides of fingers, toes, soles and palms. The disease develops progressively into continual scaling, peeling, cracked skin, bleeding, deep fissures and open wounds that do not heal. Dyshidrosis can exist as a chronic or recurring condition, and in some individuals it can persist for many years. Intermittent flare-ups tend to occur after extended periods of stress or emotional conflict. Although it is not known what causes the disease, dyshidrosis and other forms of hand dermatitis, are thought to be related to stress, anxiety or contact with some form of irritant or allergen (Lehucher-Michel, M. P., Koeppel, M. C., Lanteaume, A., Sayag, J. Contact Dermatitis 2000 43 (4):200-5).

While topical steroidal or non-steroidal immuno-suppressive agents remain the primary treatment for dyshidrosis, atopic dermatitis and psoriasis, they don't address the etiology of the disease and some individuals do not respond to prescriptive medicines. Moreover, local and systemic side effects are risks with extended use. If the condition is non-responsive to available medicine, lifestyle alterations for those suffering with pompholyx could include being confined to cotton lined gloves and avoiding direct contact with ubiquitous substances such as soap, water, detergents, paints, polish and chemicals. Moreover, there could be a potential loss of functional utility of the hands and/or feet. Open wounds require constant care to maintain asceptic conditions and apply bandages. And, since soap and water worsen the condition of this disease, it becomes quite difficult to maintain a sterile environment proximal to the site of injury.

Options available to those diagnosed with pompholyx or related skin diseases, who do not respond to steroidal anti-inflammatory agents are limited. The use of standard ultraviolet (UV) therapy (WO 02/055149, Oct. 22, 2001, Irwin and Altman) and subsequent modifications have been patented to treat dyshidrosis (U.S. Ser. No. 2002183811, Dec. 5, 2002, Irwin). The effects of UV therapy have been moderately successful, and in patients with non-responsive dyshidrotic eczema, approximately 31% establish complete remission, 33% exhibit partial remission and 36% exhibit no change (Douwes, K. E., Karrer, S., Abels, C., Landthaler, M., Szeimies, R. M. Photodermatol Photoimmunol Photomed 2000 16:25-9). For this reason, there is a need to investigate alternative topical agents to treat this and similar diseases of the skin, to which there are no effective treatments.

The embodied invention describes a useful formulation that can effectively establish remission of dyshidrosis, non-responsive to prescriptive topical medicine. These are preliminary findings, and warrant further research and investigation. To date, there are no integrated topical herbal formulas described to treat dyshidrosis or similar conditions such as exfoliative keratolysis and palmoplantar pustulosis. There are, however, patented therapeutic approaches described to treat dyshidrosis with vitamin E analogues (WO-97/45098, Jun. 02 1997, Panin), sulfhydryl acyl derivatives (U.S. Pat. No. 4,721,705, Jan. 26, 1988, Schreuder), oral administration of salts and esters of cis retinoic acid (U.S. Pat. No. 6,589,989, Jul. 8, 2003, Bollag, et al.) and topical steroids (U.S. Pat. No. 4,891,386, Oct. 15, 2002, Dykstra). Alternatives to treat pompholyx, have also included using an isolated extract derived from the bark of a southestern Asian plant called the citrus decumana tree (JP-6340541, Dec. 13, 1994, Tashiro Eiichi) and fresh pine needle (CN-1113795, Dec. 27, 1995, Chunyang et al.).

The embodied invention discloses a novel topical formulation, found effective in establishing complete remission in a pilot trial of severe dyshidrosis, non-responsive to current prescription medicines and over the counter ointments. Moreover, the formula was found to be effective in rapidly suppressing and reversing initial symptoms of outbreak. Results indicate that therapy can be discontinued after remission is established. The principles governing development of the embodied formulation were based on observations regarding pathological symptoms of the disease: A) this skin disease stops at the perimeters of the hands and feet, indicating reduced circulation or blood flow may play a role B) this condition appears to involve an unknown factor, with an intermittent nature, that thrives on both moisture and flesh, possibly a virus C) this condition escapes capability of our immune system to destroy it and D) there is extensive skin loss, somewhat similar to a second degree burn. For these reasons, the topical ointment was formulated to (1) contain anti-microbial: anti-parasitic, anti-bacterial, anti-protozoal, anti-fungal and anti-viral properties to destroy or inhibit the growth of invading pathogenic organisms or potential unknown retroviruses (2) contain dermal anti-inflammatory agents: effective cyclooxgenase inhibitors/lipoxygenase inhibitors, and compounds that attenuate local dermal eicosanoids and prostaglandins to reduce the swelling, redness and pain (3) contain cutaneous vasodilators that inhibit thromboxanes, and increase local endothelial nitric oxide to increase blood flow to the area of injury (4) contain aloe vera gel as a base in order to promote rapid healing of damaged or lost skin tissue and (5) contain compounds that destroy or remove dead skin, which appear to correlate with rapid healing.

The embodied invention is unique, and its formulation was based on pharmacological scientific principles rather than literature describing common herbs that are good for the skin. While there are a number of herbal creams on the worldwide market available for the treatment of skin disorders, few contain the active ingredients as described in this invention. Moreover, it has been reported that many marketed herbal topical skin products, either don't work or they are misleading, claiming to be natural, but adulterated with potent steroids. Interestingly, according to an article on Tuesday, 9 Dec. 2003 BBC News Entitled “Steroids in herbal eczema creams”, in a small scale study, 20 out of 24 herbal creams sold for treatment of eczema, contained potent steroid drugs, some labeled under the ingredient “Wau Wa”, components that were really pharmaceutical grade steroids in a paraffin base. The reporter indicated that he would be surprised if any “herbal cream could rapidly eradicate eczema”. There are also other reports that indicate a similar pattern where herbal creams sold over the counter, have been adulterated with agents such as topical zinc pyrithione or clobetasol propionate, which in some places are banned or illegal.

A review of the literature regarding skin creams that are sold and marketed, indicate that many herbal creams have analogous constituents, that are commonly known as skin remedies. Common ingredients in herbal skin creams include burdock, dandelion, lavender, marigold, marshmallow, nettle, violet, rosemary leaf, lemongrass, rosewood, sandlewood, yarrow, tea tree, geranium, chickweed, myrrh, yellow dock, golden seal, birch, calendula, echinacea, goldenseal, red clover, comfrey, and witch hazel or colloidal silver. Common herbal ointments include variations and combinations of these ingredients, such as, ZenMED natural eczema treatment system (zenmed-natural-herbal-eczema-treatment-cure.com), which contains the active ingredients borage oil, calendula, chamomile, viola, dog rose, echinacea, tea tree oil, vitamin A, C, E, bioflavonoids, kukui oil, lavender, geranium and tangerine. Another breakthrough herbal cream for eczema (Attogram Corp.), contains oils of cedarwood, chamomile, eucalyptus, lavender, palmarosa, rose, tea tree, castor, olive, colloidal silver, citric acid and lanolin. And, many variations have been described in herbal skin ointments such as combinations using comfrey, tea tree, witch hazel, dandelion, goldenseal, lavender, yellowdock (community-2.webtv.net), dandelion, goldenseal, red clover; yellow dock (sunthymeherbfarm.com), yellow dock, red clover or cleavers (viable-herbal.com), brewers yeast, nightshade and red clover (target.com), hawthorn, licorice, burdock, chamomile, ginkgo, gotu kola, echinacea, comfrey, dandelion, marshmallow, red clover etc. (herbs.org), goldenseal, kelp, myrrh, red clover, Pau d'arco, dandelion and yellow dock root (drcureme.com). The topical cream Florasone (herbalremedies.com) claims to be the first natural alternative to cortisone creams introduced in the United States and contains the active ingredient comprised of extract of Cardiospermum. And, other skin tonics such as those that treat herpes simplex, scabies, dermatitis, eczema and fungal infections are comprised of unique herbs such as cortex phellodendri, radix sophorae flavescentis, Rhuctus chidii and rhizoma atractylodis (herbalhealer.com).

According to a review of prior art, the embodied formula is novel in terms of its unique combination of powerful ingredients, and specific utility to ameliorate dyshidrosis and similar skin disorders such as palmoplantar pustulosis and exfoliative keratolysis. The primary ingredients within the formula include a combination of dry, aqueous, acid or alcohol extracts of black walnut hull (Juglans Nigra), wormwood (Artemisia Absinthium), tumeric rhizome (Curcuma Longa), garlic (Allium sativum), chamomile (Matricaria Chamomile), licorice root (Glycyrrhiza Glabra), St Johns wort (Hypericum perforatum), aloe vera, niacin or its derivatives and one or more herbal antibacterial agents. This combination of ingredients, as a composite, was also found to be lethal to bacteria, fungus, mold and yeast, indicating its use may include an expansive range of skin disorders associated with invasive pathogens. The formula is comprised of cooking spices and components that are often taken orally by humans, therefore the ingredients should be relatively safe, with exception of potential allergic sensitivity reactions that may occur. The following is an introduction of circumscribing prior art for each ingredient in the formula as it applies to topical applications of the skin.

INGREDIENT 1: Extracts of wormwood or artemesia are often incorporated into complex formulas that comprise agents directly applied to the skin, such as aftershave lotion (RU-2109506, Apr. 27, 1998 Dolotovskij et al.,), facial cleanser (RU-2124350, Jan. 10, 1999, Detsina et al.,; CN-1236610, Dec. 1, 1999, Liu), wrinkle reduction cream (CN-1110132, Oct. 18, 1995, Zhongxin), muscle pain ointment (U.S. Pat. No. 6,579,543, Jun. 17, 2003, McClung), treatment for warts (U.S. Pat. No. 5,576,005, Nov. 19, 1996, Wise , et al.) and anti-aging formulas that promote synthesis of collagen (JP-206835, Jul. 31, 2001, Sasaki et al.).

Wormwood is known for its anti-parasitic effects, and if taken internally can promote bowel movement, improve digestion and enhance blood circulation. Previous research on therapeutic use for wormwood and artemisinin, primarily focus on its efficacy as an anti-malarial compound. There is little to no technical research, documenting the efficacy of wormwood, relevant to skin diseases. There are, however, topical agents patented for treatment of dry skin that have included wormwood as a minor component in a list of ingredients. Of these include: wormwood 1) listed with 12 other herbal constituents that comprise a secondary tincture to be combined with a primary herbal extract base consisting of rowan melanocarpous, bird cherry and rose fruit, and a pretreatment of Siberian fir coniferous needles and sea-buckthorn juice for treatment of dermatitis (RU-2124363, Jan. 10, 1999, Tereshchenko et al.,) 2) in combination with pine needle, dark plum, peppermint, acetic acid, borneol and bezoar, for treatment of dermatitis (CN-1360899, Jul. 31, 2002, Lan) 3) artemisia capillaris incorporated in to a base formula of ω3 and ω6 fatty acids as one of approximately 30 optional herbal extracts to treat dry skin, inflammation, rash and itching (JP-063942, Mar. 5, 2003, Shizuka et al.,) and 4) at very low concentration, (approx 0.1-0.5% wormwood) in combination with glycerine, propolis extract, oil of common origanum, polyethyleneoxide gel, egg yolks, horsetail decoction, bergenia, plantain, citric, salicylic acids, henx salts, benzoate for treatment of fungal and microbial infections of the skin (RU-2118152, Aug. 27, 1998, Detsina et al.). It has been reported that the tricyclic sesquiterpene, artemisinin and its derivatives (chemicals found naturally in wormwood) may be effective in treating psoriasis, dermatitis, dyshidrosis and eczema (U.S. Pat. No. 5,057,501, Oct. 15, 1991, Thomfeldt). These findings indicate that beneficial effects observed in treatment of pompholyx, may be due to artemisinin and related chemicals within the extract of wormwood.

INGREDIENT 2: Black walnut (Juglans Nigra). While the toxicity of black walnut in equine has been investigated, there is little to no research documenting the use of Juglans Nigra to treat either infectious or non-infectious skin disorders. Further, there is meager patent literature describing the use of black walnut or Juglans Nigra incorporated into topical creams or cosmetics, with exception of its use as a germicidal agent incorporated into chewing gum, deodorant gel and foot powder (U.S. Pat. No. 5,137,717, Aug. 11, 1992, Wixforth). Although there is little documentation in either research or patented literature, historical herbal literature indicates that black walnut is known to treat intestinal parasites, worms, warts, growths, eczema, psoriasis, lupus, herpes, and skin parasites. Interestingly, black walnut is not a common ingredient amongst herbal preparations marketed or sold for treatment of skin.

INGREDIENT 3: St. John's wort (Hypericum perforatum) is often incorporated into topical formulas that comprise weight loss cream (U.S. Pat. No. 4,795,638, Jan. 3, 1989, Ayache et al.), anti-aging cosmetic (U.S. Pat. No. 4,911,925, Mar. 27, 1990, Shatkina et al.), lotion (EP-1291011, Mar. 12 2003, Leonidov et al; RO-116865, Jul. 30, 2001, lonita-Manzuta et al.), facial cleanser (U.S. Pat. No. 6,342,208, Jan. 29, 2002, Hyldgaard et al.), topical treatment for acne and chapped skin (JP-04-124138, Apr. 24, 1992, Yan et al.), bum ointment (CN-1179950, Apr. 4, 1998, Mo Xiaochun), treatment for fungal infections of the nail (GB-2311009, Sep. 17, 1997, Khan Mohd Taufiq) muscular pain relief lotion (U.S. Pat. No. 6,579,543, Jun. 17, 2003, McClung), arthritis pain reliever (U.S. Pat. No. 6,573,302, Jun. 3, 2003, Holt et al.), moisturizer (JP-60-258104, Dec. 20, 1985, Yuchi et al.,) and lotions with smoothing, firming and UV protection properties (U.S. Pat. No. 5,560,917, Oct. 1, 1996, Cohen et al.).

St. John's wort has also been used in the past, as a remedy to treat wounds and burns (Schempp C M, Muller K A, Winghofer B, Schopf E, Simon J C. Hautarzt. 2002 May;53(5):316-21). Hyperforin, a primary constituent of St. John's wort is effective in treating atopic dermatitis (Schempp C M, Windeck T, Hezel S, Simon J C., Phytomedicine. 2003;10 Suppl 4:31-7.), possibly through anti-inflammatory properties (Schempp C M, Winghofer B, Ludtke R, Simon-Haarhaus B, Schopf E, Simon J C., Br J Dermatol. 2000 May;142(5):979-84.). St. John's wort has also been used as a constituent in topical agents for treatment of dry skin as it relates to photo damage effects of the sun. Of these, include its use in combination with branches and leaves of olive, glycyrrhetinic acid and allantoin (JP-183146, Jul. 03, 2003, Hikima et al.) and in combination with asparagus extract, chamomile, Lithospermum erythrorhizon, Lonicera japonica, sage, birch, Calendula officinalis, elder tree, flag, glycyrrhizic acid, guaiazulene, aminocaproic acid and their derivatives (JP-06-128145, May 10, 1994, Hayashi et al.).

Relevant prior art pertaining to the use of St. John's wort include 1) the use of extracts of St John's wort depleted of chlorophyll for treatment of acne, viral infections and psoriasis (DE-10131641, Jun. 27, 2002, Koch et al.,) 2) its use with or without Tilia miqueliana extract to treat contact dermatitis, allergic skin reactions and rough skin (JP-09-157176, Jun. 17, 1997, Nishibe) and 3) St. John's wort added to a base formula of co3 and co6 fatty acids, as one of 30 optional herbal extracts to treat dry skin, inflammation, rash and itching (JP-063942, Mar. 5, 2003, Uehara Shizuka et al.).

INGREDIENT 4: TURMERIC (Curcuma Longa) has been incorporated into topical skin lightening and UV protective lotion (WO 03/030814, Apr. 17, 2003, Muhammed et al.), treatment for acne (CA-2353057, Jan. 13, 2002, Khaiat; U.S. Pat. No. 6,277,881,Aug. 21, 2001, Santhanam et al.), treatment for skin discoloration and hemorrhoids (U.S. Pat. No. 6,048,533, Apr. 04, 2000, Nguyen Van Bich), ointment that relieves soreness and muscle discomfort (U.S. Pat. No. 6,579,543, Jun. 17, 2003, McClung), lotion that protects against environmental toxins (U.S. Pat. No. 6,521,668, Feb. 18, 2003, Anderson et al.) and treatment for wounds and ulcers (U.S. Pat. No. 5,401,504, Mar. 28, 1995, Das et al.).

Turmeric is an anti-inflammatory agent and when applied to the skin, has shown to reduce dermal inflammatory promoters such as arachidonic acid, cyclooxygenase, lipoxygenase 5-hydroxyeicosatetraenoic acid and pro-inflammatory prostaglandins (Huang, M. T., Lysz, T., Ferraro. T., Abidi, T. F., Laskin, J. D., Conney, A. H. Cancer Res 1991 51:813-9.; Huang, M. T., Newmark, H. L., Frenkel, K. J Cell Biochem Suppl 1997 27:26-34). Curcumin also contains inherent antiviral properties (Barthelemy, S., Vergnes, L., Moynier, M., Guyot, D., Labidalle, S., Bahraoui, E. Res Virol 1998 January-February;149(1):43-52; De Clercq, E.Med Res Rev 2000 20:323-49) and is effective against tumor promoting viral agents, such as Epstein-Barr virus and herpes simplex virus type 2 (Kapadia, G. J., Azuine, M. A., Tokuda, H., Hang, E., Mukainaka, T., Nishino, H., Sridhar, R. Pharmacol Res 2002 45:213-220.; Boume, K. Z., Boume, N., Reising, S. F., Stanberry, L. R. Antiviral Res 1999 42:219-26). Moreover, turmeric has a number of other pharmacological properties such as anti-bacterial, anti-parasitic and antispasmodic (Araujo, C. C., Leon, L. L. Mem Inst Oswaldo Cruz 2001 96:723-8).

Prior art describing the use of turmeric as a constituent in topical agents for treatment of dry skin include: its use as a minor ingredient 1) in combination witn hydroxy acids, vitamin E, vitamin B, glycolic acid, antioxidants, hormones, and oils to treat psoriasis, dryness, itching, stretch marks, and microbial infections (U.S. application Ser. No. 2003113388, Jun. 19, 2003, Phan) 2) in combination with triclosan, phenoxy ethanol, benzalkonium chloride, benzethonium chloride, cocophosphatidyl-dimonium chloride for the treatment of skin inflammations, redness, pain, exudate, and bacterial infections (U.S. Pat. No. 6,248,343, Jun, 19, 2001, Jampani et al.), 3) at a low concentration (0.1-1%), as an optional anti-inflammatory compound incorporated into a base of carbopol, emulsifiers, preservatives, and humectants containing Tridax procumbens extract and gum olibanum powder the treatment of cracked heels, dry skin disorder, skin allergies, depigmentation, burns, wounds and fungus (U.S. Pat. No. 6,379,673, Apr. 30, 2002, Diwan et al. ) 4) in combination with ω3 and ω6 fatty acids for treating dry skin, inflammation, rash and itching (JP-063942, Mar. 5, 2003, Uehara Shizuka et al.,) 5) incorporated as an optional ingredient selected from a list of herbs into a base of dihydric alcohol solution, as an antibacterial skin preparation (JP-145793, Mar. 22, 2002, Kobayashi Kayoko et al.,) and 6) in combination with a base comprising hydroxy acid and retinol deriviatives, for treating skin inflammation and irritation (JP-002559, Jan. 9, 2001, Santanamu et al.,). In documents where turmeric comprises a primary component, (JP-09-143086, Jun. 3, 1997, Masayoshi), a fat-soluble extraction procedure for turmeric has been described, introducing a carrier system of vegetable oil for treatment of skin diseases such as eczema, acne, atopic dermatitis, chapped skin or general.

INGREDIENT 5: Propolis is an optional ingredient in this formula. It was not incorporated into the base formula as tested, however, it may be used as a substitute to replace ingredients that may otherwise cause allergic skin reactions such as garlic, or to enhance efficacy or aesthetic properties. Propolis has been used in formulations that comprise beauty lotion, or regenerative skin cosmetic (RU-2166313, May, 10, 2001, Dolotovskij et al.), deodorizer (RU-2185808, Jul. 27, 2002, Khismatullin), moisturizing cream (RU-2161029, Dec. 27, 2000, Kravchenko; JP-10-194948, Jul. 28, 1998, Yamamoto), wrinkle removing cream (RU-2161029, Dec. 27, 2000, Zhang; CN-1268348, Oct. 4, 2000, Tong), bug repellent, skin cleanser, germicide (CN-1263146, Aug. 16, 2000, Liu Fuhai Xu et al.) exfoliation cream (U.S. Pat. No. 6,416,769, Jul. 9, 2002, Vromen), skin whitener (U.S. Pat. No. 6,269,817, Aug. 7, 2001, Nagashima et al.) tanning solution (U.S. Pat. No. 6,171,605, Jan. 9, 2001, Bevacqua et al.) bum ointment (JP-07-304684, Nov. 21, 1995, Longchamp), treatments for acne and dandruff (JP-59-118702, Jul. 9, 1984, Takashi et al.) and treatment for skin fungal infections, such as candidiasis (RU-2118152, Aug, 27, 1998, Detsina).

There is documented evidence that topical application of propolis can aid in the healing of bum wounds (Gregory, S. R., Piccolo, N., Piccolo, M. T., Piccolo, M. S., Heggers, J. P. J Altern Complement Med 2002 8:77-83). Moreover, propolis has several medicinal properties, including it ability to serve as an analgesic, anti-flammatory agent, and ameliorate symptoms of psoriasis (Ledon, N., Casaco, A., Gonzalez, R., Merino, N., Gonzalez, A., Tolon, Z. Zhongguo Yao Li Xue Bao 1997 18:274-6; Park, E. H., Kahng, J. H. Arch Pharm Res 1999 22:554-8). Propolis is also a powerful antibacterial and antifungal agent, with efficacy demonstrated against a large variety of pathogens (Ota, C., Unterkircher, C., Fantinato, V., Shimizu, M. T. 2001 44:375-8; Drago, L., Mombelli, B., De Vecchi, E., Fassina, M. C., Tocalli, L., Gismondo, M. R. J Chemother 2000 12:390-5; Koo, H., Gomes, B. P., Rosalen, P. L., Ambrosano, G. M., Park, Y. K., Cury, J. A. Arch Oral Biol 2000 45:141-8).

Propolis as a constituent has been used in topical agents for treatment of dry skin and/or bacterial infections, some of which include its use 1) in combination with an inert base, arnica montana, woody aloe, marigold and at least one antibiotic selected from detromycin, bacitracin, neomycin, polymyxin etc. for ameliorating burns (WO 02/076411, Oct. 3, 2002, Dorian) 2) in combination with olive oil, sea buckthorn-seed oil, beeswax, dog rose oil, St. Johns wort oil extract, peony root oil extract, bergenia oil extract to treat wounds (RU-2195258, Dec. 27, 2002, Repjakh) 3) in combination with honey, apricot seed extract and royal jelly to treat discoloration, wounds, burns, miliaria and eczema (KR-20010008260 A, May 2, 2001,Kim), 4) in combination with Balsaminaceae to treat skin allergies and atopic dernatitis (JP-11-322620, Nov. 24, 1999, Sakamoto et al.) 5) in combination with pyrolignous acid, chitin chitosan and garlic for treatment of parasitic atopic dermatitis, athlete's foot, scabies, dermatophytosis, candidiases, scabies, tinea cruris or serpigo (JP-10-175878, Jun. 30 1998, Otsuka et al.) and 6) in combination with alcoholic-glyceric nettle, chelidonia, oak bark, willow bark, calendula, dandelion roof, camomile, achillea, dill, parsley, thyme oil, lemon oil etc, for treatment of psoriasis (WO 01/66079, Feb. 28 2001, Bodnar et al.).

No. 6,299,890, Oct. 9, 2001, Russ et al.), lotion (U.S. Pat. No. 6,589,514, Jul. 8, 2003 Jensen et al.), moisturizer (U.S. Pat. No. 6,579,516, Jun. 17, 2003, Mansouri), tanning solution (U.S. Pat. No. 6,482,397, Nov. 19, 2002, Scott et al.), exfoliation cream (U.S. Pat. No. 6,416,769, Jul. 9, 2002, Vromen), anti-aging and whitening cream (U.S. Pat. No. 5,393,526, Feb. 28, 1995, Castro), skin cleanser (U.S. Pat. No. 6,221,372, Apr. 24, 2001, Golz-Bemer et al.) acne treatment (CA-2353057, Jan. 13, 2002, Khaiat), revitalizing, smoothing, moisturizing cream (U.S. Pat. No. 5,876,736, Mar. 2, 1999, Cohen et al.), arthritic pain reliever (U.S. Pat.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following discloses a formulation for treatment of dyshidrosis, and other dry skin or infective skin disorders. The formula is comprised of a combination—selected from the group of active ingredients consisting of aqueous, acid or alcohol extracts black walnut (Juglans Nigra), wormwood (Artemisia Absinthium), turmeric rhizome (Curcuma Longa), garlic (Allium sativum), chamomile (Matricaria Chamomile), licorice root (Glycyrrhiza Glabra), St Johns wort (Hypericum perforatum), niacin, aloe vera alone or in combination with dermatologically acceptable carrier and optional herbal anti-bacterial agents such as nutmeg, myrrh or clove. The demonstrated utility of the embodied invention should not be interpreted to limit the scope of the invention with regards to application, use or treatment as it relates to skin disorders of analogous symptomatic pathologies.

The practical utility of this invention was demonstrated in a case study of a patient diagnosed with classic dyshidrosis, non-responsive to prescriptive topical applications. The initial symptoms of the disease appeared as little white blister formations on the patients hands, that proliferated rapidly in number and area, spreading down the fingers and toward the palms on both hands. Despite daily therapy with prescriptive topical steroids, the condition worsened rapidly and within a short period of time (˜1 month), there was extensive peeling, cracked dry skin, skin loss, scales, fissures, open wounds and bleeding. Gradual worsening and non-healing of skin tissue was similar to and approaching the condition as depicted in a standard diagnostic photograph of developed dyshidrosis (FIG. 1A,B). The skin on the finger tips of this patient was completely gone, and fingerprints were indistinguishable. The patient was confined to wearing white cotton gloves, bandages, and was restricted from contact with soap and water. Prescription medications were ineffective, and any type of moisturizing cream could not be applied, without causing pain. The condition was debilitating and resulted in the loss of use of both hands. With gradual worsening, the patient also tried several over the counter triple antibiotic ointments and anti-fungal agents, all of which were ineffective. All medications were discontinued and the formulation as described in this embodiment was applied topically.

Within a week, the body's natural skin moisture appeared to be restored. The redness, pain and bleeding had stopped, and the skin started to heal. Due to extensive skin loss,—equivalent to a 2^(nd) degree bum, the healing time was dependent upon the extent of skin loss, where the inherent nature of the disease appeared to be eliminated. Complete recovery was achieved in a relatively short period of time, and treatment was discontinued. The patient now lives free from this disease, and any flare-up can be rapidly eradicated with the embodied invention. Individuals, that do not respond to treatment, often live with this disease, for years to decades. In a follow up investigation, on two separate occasions within the next several years, approximately 5-10 little white blister formations emerged on the finger tips of the patient, synonymous with initial symptoms of a relapse (See FIGS. 1C-G). The topical agent was immediately applied and found to be effective in halting the outbreak and establishing remission. One finger was left untreated for 48 hours, and exhibited progressive blister formation (FIGS. 1C-E), which could rapidly deteriorate into a serious condition as demonstrated in FIG. 1A. Upon treatment, the skin was rapidly restored to its normal healthy tissue, corroborating that therapeutic effects were due directly to the treatment, and not a spontaneous remission.

Because the treatment was effective in both halting and reversing an acute progressive disease state, the findings warrant further investigation to evaluate efficacy and variation of this formula to treat not only pompholyx, but similar dry skin disorders. Moreover, the formulation as a composite, was evaluated for toxicity to invasive pathogens. And, at extremely dilute concentrations (<1% of working concentration), the formulation was lethal to bacteria, fungus, mold and yeasts such as Streptococcus pneumoniae, Candida parapsiolosis, Cryptococcus neoformans and Aspergillus fumigatus. These findings indicate a potential beneficial effect against skin disorders that are initiated by invasive pathogens.

The formulation is to be applied topically, and its utility is for the prevention and/or treatment of pathological conditions of the skin. Pathological conditions of the skin, herein referred to as “pathological conditions” “conditions”, “skin conditions” and “skin disorders” are defined as symptoms present anywhere on the skin, characterized by mild or extremely dry skin, skin lesions, cracks, fissures, scaling, discoloration, thickening, redness, bleeding, swelling, flaking, ulcers, sores, wounds, blistering, rashes, loss of flesh or similar. In particular, these would include skin disorders that affect the feet and hands, such as pompholyx, palmoplantar pustulosis and keratolysis exfoliativa.

The aforementioned pathologies also include “skin disorders” classified under dermatitis including but not limited to: atopic, contact, hand, allergic, gravitational, asteatotic, nummular, seborrhoeic, infective, chronic superficial scaly acrodermatitis, chondrodermatitis and perioral dermatitis. This would also include autoimmune or drug induced dermatomyositis, or similar conditions associated with internal pathologies such as neutrophilic dermatosis, dermatomyositis or transient acantholytic dermatosis. Skin disorders also include those classified under eczema and associated with inherited or metabolic conditions including but not limited to ichthyosis, xerosis or asteatosis. And, dry skin conditions including psoriasis, lupus erythematosus, exfoliative keratolysis and any type of allergic inflammation of the skin such as urticaria.

The formula as a composite, is lethal to bacteria, fungus, mold and yeast and can be used to treat and/or prevent dermatological diseases in the presence or absence of the aforementioned symptoms, caused by various pathogens. Pathological skin conditions include those incurred by 1) yeasts; including but not limited to malassezia and candida 2) fungus; including but not limited to dermatophyte fungi; trichophyton, epidermophyton, microsporum, tinea and tinea affecting all areas of the body such as tinea barbae, capitis, corporis, cruris, manuum, pedis, and unguium 3) bacteria; including but not limited to those caused by staphylococci being folliculitis, furunculosis, staphylococcal scalded skin syndrome and streptococci being erysipelas, impetigo, necrotising fasciitis or ecthyma 4) parasites; including but not limited to mites, scabies and lice 5) molds; including but not limited to scopulariopsis, aspergillus, fusarium, scytalidinium 6) viral agents; including but not limited to coxsackie enterovirus, herpes, parvovirus, Epstein barr 7) any type of unknown skin disease such as Lichen planus and/or 8) any type of known or unknown skin disease to which there are no current effective treatments. The embodied invention may be useful as a multi-purpose ointment.

Preparation of the formula for the treatment and prevention of aforementioned skin disorder, may vary to achieve desired effects on the skin. While the best mode has not been investigated thoroughly, a working concentration base range has been established. Briefly, the formula is partially comprised of herbal components prepared by extraction procedure. A specified portion of each herbal plant (as indicated below) can be used, however this is not limited to experimenting with various other parts of the natural plant including the root, seed, nut, stalk, bark, vegetable, fruit, hull, bud, leaf, flower, bulb or entire. Pure fresh herbs are slowly dried at very low temperature, and macerated into an extract, typically comprised of one or more of the following: grain alcohol, distilled water, glycerine or vinegar. Extracts are the solvent in which herbal components are prepared, and may include any solvent that can be used to maximize therapeutic value, or commercial production feasibility at the discretion of one skilled in the art. These also include any liquid, chemical, alcohol, lipophilic oil based solvents or acetone. Depending upon the strength of the herbal extract, dry herb menstrumm ratios can vary (w/v) between 1:5-4:5. Typically herbal extracts are stored in a sterile closed container (glass or suitable), in a warm dry area, away from light for about 0.5-2 weeks with intermittent stirring. The extract is then filtered to remove particulates and stored at a cool temperature in an amber container to prevent exposure to light.

The herbal extracts are then combined with niacin and garlic, into a base carrier of pure aloe vera gel and optionally a dermatologically acceptable carrier. The development of a marketable skin care product would require incorporation of chemical ingredients that comprise a commercially feasible dermatologically acceptable carrier. These may include substances such as surfactants, binders, emulsifiers, stabilizers, preservatives, emollients, foaming agents, sweeteners, thickeners, surfactants, coloring agents, fragrances, lipids, additives, solvents, moisturizers, lubricants, carriers, bulking agents, deodorizers, buffers, or the like. Furthermore, the product as a whole may constitute a variety of delivery and product consistencies, including but not limited to, a suspension, solution, dispersion, lotion, liquid, gel, stick, capsule, foam, cream, pack, paste, coated glove or sock, spray, aerosol, ointment, sponge, gel cap, granule, bandage, gauze powder or any other type of bio-delivery system or improvements thereof. The ingredients that comprise a working example of the formula, as listed below are presented as % total weight herein specified as “% TW” with extended (EXT) ranges.

Chem Pharm Bull (Tokyo). 2003 September; 51(9):1081-4 and Dolara et al. Planta Med. 2000 May; 66(4):356-8.]. Therefore addition of similar herbs with similar bacteriostatic nature given the provision for option herbal antibacterial agents would not constitute new matter. Further, we have recntly done studies in our lab usingfrankincense, and found this herb to be equi-potent to myrrh. If examiner finds this to be new matter, we can delete it from the amended claims, and continue prosecution on the merits.

The formulation may vary with intended use, sensitivity of skin, age range, allergies, mammal species and illness classification. While a working example has been described above for human skin, alternative formulations may include preparation using fresh, dry, solid or aqueous preparations of active ingredients and variation in plant species amongst each genus. A larger concentration range could account for a therapeutically effective amount that may constitute a near pure solution of the active ingredients within the formula. Moreover, variation in formulation will be required to suit mammal species. For example, for treatment of feline skin disease, compounds such as aloe vera, garlic and wormwood are known to be toxic to cats, and would not be safe. Therefore, modification of the formula would be required, using ingredients such as turmeric and black walnut, which are safe and effective.

The best mode for carrying out the invention as described above, is not limited to the altering, substituting or adding of constituents, or variation in extraction procedures within the scope of the invention. To one skilled in the art, various modifications of the invention, without departing from the scope may include: 1) altering the % weight of each constituent 2) incorporating new components to optimize efficacy or commercial processing 3) altering the extraction time, conditions or temperature 4) introducing isolated chemical compounds derived from each plant extract individually or in combination to produce similar or better therapeutic results 5) or changing the formulation by subtracting aforementioned ingredients or using various combinations.

Improved efficacy for severe skin conditions has been achieved by initially applying the topical ointment to the skin, and covering the skin with plastic gloves overnight. In the morning, the hands can be washed, and the formula applied throughout the day. Variation in topical application will depend upon extent of disease, sensitivity, therapeutic response, age, body weight, concentration and bioavailability of active ingredients. While the results from our study, indicate therapeutic value of this formulation, significant future research will be required to elucidate efficacy and possible allergic skin reactions that may occur in susceptible individuals. Previous research has indicated that dermatological side-effects can occur in select individuals in response to St John's Wort, aloe vera, chamomile and garlic (Ernst, E. Br J Dermatol 2000 143:923-9; de la Torre Morin, F., Sanchez Machin, I., Garcia Robaina, J. C., Fernandez-Caldas, E., Sanchez, Trivino, M. J Investig Allergol Clin Immunol 2001 11:118-22; Jappe, U., Bonnekoh, B., Hausen, B. M., Gollnick, H. Am J Contact Dermat 1999 10:37-9.). For this reason, a 48 H skin patch test on the armpit, and arm is advised before using. And, topical treatment to the site of injury should be scheduled in gradual dose increments.
